JULIUS .H. BACH, OF'CHICAGO, ILLINOIS.

ArrARA'rUs FOB rAoiLrrA'rmG THE BURNING or BRICK.

To all whom it may concern:

Be it known that I, JULIUS H. BACH, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus for Facilitating. the Burning of rick, of which the following is a description, reference being had to the accompanying drawings, forming a part of this specification, in which corresponding numerals of reference in the different' figures indicate like parts.

The object of my invention is to provide an apparatus to facilitate the burning of bricks in kilns whereby the operation may be rendered continuous andthe heat and prodnets of combustion from the burning kiln may, after being utilized for dryingthe green brick preparatory to burning, be carried off to a stack so as .to fully conserve the heat generated while preventing the dissemination of smoke and obnoxious gases which have heretofore attended the burning of brick in the open air. To these ends my invention consists in the combination of elements hereinafter more particularly described and definitely pointed out in the claims.

In the drawings Figure l'is an end view of shed-and kiln showing the improved apparatus in connection therewith. Fig.' 2

is a plan view of a kiln, drying room and stack, together with said improved apparatus, diagrammatically shown. Fig.3 is a side elevation ofa portion of a kiln showin the movable hood and heat conduit. Fig. 4.

is an end view in detail of a portion of that end of the hood which is adjacent to-the conduit, the relative position of the latter being indicated in dotted lines, and Fig. 5 is a vertical section, taken upon the line 5 Fig. 4:, viewed in the direction of the arrow there shown.

Referring to the drawings, 1, Fig. 1, represents an ordinary kiln shed having the usual parallel rows of posts 2, which are extended lengthwise thereof and between which the kiln 3, of indefinite length is placed. Within and adjacent to the posts and rigidly connected therewith by means of ties 4, are supplemental posts 5, the upper ends of which are considerably above the level of the top of the kiln and serve, among SPCClfiOB-tidlidftf Letters Patent.

. erally designated in theseveral figpresby 9, is mounted at opposite ends on w eels 10, which are adapted to travel upon the tracks 8. The width of the hood is somewhat greater than that of the kiln, at thetop,

but its length may be indefinite. I prefer, however, that it should be made to extend over about five or six of the ordinary arches 11, Fig. 3, of the kiln.- Said hood is prefer- ,1 ably composed of a plurality of arched por-i tions'12, extending transversely of thekiln, said arched port-ions being formed consid erably higher at one end than at the other, as shown in Figs. 1 and 3. The left handend of the hoodis closed by means of an end plate 13, Fig. 3, the lower edge of which is straight, while bottom plates 14=and 15,

the latter of which is also shown in Fig.5, are attached thereto and extended lengthwise of.the kiln so as to project laterally over the edges thereof. Inasmuch as the hood. is adapted to travel upon a horizontal track lengthwise of the kiln, the height of the latter when built, should be adapted to that of the hood and: its upper surface should be such as to barely allow for clearance to permit the hood to be moved over it. In Fig. 1. in order to avoid possible confusion, I have shown the space betweenthe top of the kiln and the bottom of the hood to be somewhat exaggerated in appearance,

Supported on beams 16, or in any. ap-

proved way, is a horizontal conduit 17, Figs'. l, 2 and 3, preferably formed from sheet metal or other non-inflammable material, which is arrhngcd to extend parallel to and throughout the length of the kiln. Connected with said conduit-and extending laterally therefrom upon the side next to the kiln, are a series of intake pipes 18, the distanee between which corresponds to that between the arches 11, so that the arches of the pipe 18. Each of said intake pipes is provided with a damper 20, Fig. .5, pivoted;

in a well-known way in bearings therein,

the stem of which is provided with a crossbar 21, to the ends of which cords or chains 22, may be attached the purpose of op ning or clos ng it. The end of the hood next;

to the plate 19, is provided with an end plate 22, Figs. 4' and 5, having an openingv 23, therein the heightofqwhich 1s preterably somewhat greater. than the diameterof the pipes18,1while its length is consider-- ably g ea er than said d m t r as sh wn in Fig. 4. The pu. use of. the construction will he explained ater.

- Ail operating shaft -24, is journaled in bearings formed in brackets 25, 25, which are rigidly attached to tlle hqiid. Upon the opposite ends of Said shaft are sprocketwheels 26, 26, which are connected by means' a of sprocket-chains 27, 27, to sprocket-wheels I 28, 28, upon the hubs of two of the wheels 10. driving-wheel 29, is rigidly mounted vided with-an endless chain 30, Figs. 1 and upon one endof the shaft 24, and is pro- 4, which is adapted to be actuated by an attendant upon the. ground.

At some arbitrary point, preferably midway between the ends of the conduit .17, is located a dryingcbamber or kiln 31, Fig. 2, for drying the brick preparatory to burning it. Saidcha-mber is connected with the conduit by means of an intake pipe An outlet-pipe 33, serves to connect said drying chamber with 'a fan 34, adapted to be drivenfrom any suitable source of power. which fan is in turn connected preferably by means of an underground conduit indicated by dotted lines 35, with a chimney-stack 36, of the usual construction The operation of said device is as follows: The kiln 3 is built in the usual way with dried brick laid in open or checker work to permit the passage of heat between them. some of the upper courses thereof being la id flatwise and closer together in a well-known manner. to'partially restrain the draft at the I top, The sides and ends of the kiln are prote tcd by scoving as usual. When thus prepared thehood 9 is moved into position above the portion at the end where the fire is to be started. -A predcterminml number of arches beneatlrtlic hood are fired-when all oi the dampersj20, in the pipes 17, exceptthose communicating with the hood, are closed. When. this is done the fan 34, is

started, thereby producing a suction upwardly from thearches through the kiln to the hood 9, and conduit 17 and thence through'the drier to the stack. The heat; and products .of combustion being thereby carried through the course described. Upon burning a given section, the hood is m0ved;-.'

on andadditi-onal arches are fired until the of sufiicient length the burned portion at one end may be cooled and removed and dried brick from the drying-kiln substituted th re- -for by the time the last arches are fired at the oppositeend thereby enabling the open is dried, it be placed in the kiln ior burning. The speed of the operation may be varied by increasing or decreasing the number of arches which are being fired at a given time, it being understood that the size 'f th od may be varied and that no entire kiln is burned. By making the kiln ation to be continuous. A5 fast as the brick.

greater number of arches should be'burned than can be covered by the area of the hood.

Th eason f r ngating th Op ning 2 in the plate 22 is to insure registration between the hood and the pipes 18 while the plate 19 is to prevent cold air from being sucked into the conduit at theend of the: hood. It is obvious that the hood may be moved in either direction according to the end of the kiln at which the burning is com mcnced.

My improved apparatus not only enables the waste heat of the kiln to be utilized for drying the green brick butenables the burning to be continuous, insures a more uniform product instead of a dense volume of escapmg smoke and yapor throughout the length of the kiln; I have found in practice that only a light and oftentimes scarcely perceptible vapor escaped from the top of the .stack, which is carried ofi without injury to the atmosphere of the neighborhood.

I do not wish to be limited to the conof the conduit- 17. inasmuch as either may struction shown nor to the relative position be greatly varied withoutdeparting from thespirit of the invention.

Having thus described my invention. what I claim and desire to secure by Letters-Patout is:
